I tried: >java -cp jruby.jar org.jruby.demo.IRBConsole Exception in thread "main" java.lang.NoClassDefFoundError: jline/Completor at org.jruby.ext.Readline$Service.load(Readline.java:57) at ... at org.jruby.demo.IRBConsole.main(IRBConsole.java:64) I am running java version "1.6.0" Java(TM) SE Runtime Environment (build 1.6.0-b105) and using JRuby 0.9.2 on Windows XP Pro. Ordinary jruby and jirb work fine.
